.To all whom may concern Beilt known that I, FRANK J MILLER, 11 citieen of the. United States, and a :resident of Fostoria, in the. county oi Seneca and '5 State of Ohio, have-invented a certain .new end useful Valve-Lock; and I do hereby declare the following to be ;a full, clear,

:andexact description of the invention, such as will enable others skilled in the art to .10 which it npperteins' 'to make and use the same, reference being had to the accompanying drawings, and to .the 7 characters o'f :referenee :murked :thereon, which form -a 3PB)I"t Of this specification. I

relates. mot only to means for, locking :the

cock of the valve :to prevent rotation there ofibut else :to :means .for preventing leosenin =df the eockswhereb leakage would be :20 0t erwise pro'dueed through-the valve. The

iinvention .is "purtieula-rly useful in connecation with 'valvesor' gates which are commonly located in vpipes connecting oil 'barrels or oil tanks. .Aflgreat dealof trouble 26 'has beenexperiencedby reason of the fact that-owners ofpetroleum wells are-tempted wow open 'Vti lves for the purpose of iii-isleajdingpurc hasers of the netroleum as tea-the correct quantity of" the petroleum produced so 'b one or more wells. .The appliennt has produeedn means which will not only-lock the stop cook from turning but will also revcntwmyonetampering .w-iththe nut or ur "wliieh is commonly'used on valves "to ihohl the "cooks in position. It :has been folmd in:this.connectionfthat the burs have ibeen 1 loosened ."from the casing. by turning 1 them in: thestuds of: the. cooks nn 'd' then .by rstriking the= end of the stud the cock w ill -the *iorceki fforwiufd .n-gain'st nny locking smeiins thuttmuy be. provided. .and petroleum "will'consthntly leak by the valve and in time will cause considerable loss.

The construction may be modified by those skilled in the art, and yet such'modifications will contain the invention set forth in the claims hereinafter a pended.

Having thus described my invention, what I claim as new, and desire to secure by Letcap having arms located on each side of the ters Patent, is-

1. In a lock fora valve, a U-bar having a cap for cove'ring the nut located on the stud of the valve, and a bar extending through the valve casing, the cock of the valve, and the U-bar. i

2. In avalvelock, the combination of a U bar having a cap for covering the nut located on'thestud of the cock of the valve, a

'bar extending through the U-bar, thecasing and theicock, and means locking thc- U-bar and the bar together.

3. In a valve lock, the combination of a U-bar having a cap for covering the nut located on the stud of the cock of the valve, a bar extending through the U-bar, the casing and the cock, and means locking the Ubar and the bar together.

4. Ina valve lock, the combination of a casing, a bar extending through one of the arms, and -a plate linked to the bar and surrounding and lo ting the head of the cock and having an arm extending through the bar and the remaining arm of the cap for a locking the parts together.

In testimony whereof, I have hereunto signed my name to this specification.
